Hello, I have a small apartment and soon I will be getting a 42" plasma. I need great sound for movies and OK sound for music. I was offered the following separates combination for 850 pounds: Denon DVD-1710 Denon AVR 1705 5 B&W VM1 Speakers B&W AS1 Sub I know I can get an all-in-one for much less. Would an all-in-one of up to 450 pounds be much worst than the above setup? Or the difference is not enough to justify the extra 400? The guy that offered me the above system was also selling the Denon DHT-500SD and said that the separates is way better. What do you think?
